Hey, I'm new to the this build your own pc thing. I'm looking at the manuals for the msi mpg z390 gaming pro carbon ac motherboard and the corsair h115i pro water cooler and I noticed a problem. I plan on buying both of these products, and pcpartpicker told me that there were no compatibility issues with the two products. The h115i pro manual says "Connect pump tach cable to the CPU_FAN header on your motherboard (figure 1)" In the picture, it says "3 pin". However, in the motherboard manual, it says that there's " 1x 4-pin CPU fan connector". Are these two products incompatible? If not, where do I put the 3 pin tach cable? I appreciate any help.
